Desert Soils in Lower Wadi Howar - Evidence of climate change and human impact during the Holocene
(Leidorf2007-08-30)The analysis of desert soils near archaeological sites allowed new insights in the environmental and living conditions of the early inhabitants of the Wadi Howar (NW Sudan) and their interactions with their environment. ... -
Design and analysis of a broadband SIS-mixer for the Heterodyne Instrument for the Far Infrared (HIFI) on the Herschel Space Observatory
(Univ. Köln, 2006)In this thesis the design and analysis of SIS-mixers (SIS: superconductor-isolator-superconductor) for the use as low-noise and broad-band detectors in the submm-region for astronomical observations is described. The ... -
Designing Iron-Amended Biosand Filters for Decentralized Safe Drinking Water Provision
; Temgoua, Emile; Rahman, Mohammad A. (CLEAN - Soil, Air, Water, 2012)
There are ongoing efforts to render conventional biosand filters (BSF) more efficient for safe drinking water provision. One promising option is to amend BSF with a reactive layer containing metallic iron (Fe0). The present ... -
Designing laboratory metallic iron columns for better result comparability
; Caré, S. (Journal of Hazardous Materials, 2011)

Detailed atmospheric ice accretion surface measurement using micro-computed tomography
; (Atmospheric Science Letters, 2020)
Surfaces exposed to atmospheric cold temperature and humid environments are prone to ice accretion. Airplanes, electrical power transmission cables, and wind turbines are typical examples for which icing has to be considered. ... -
Detailed Seismic Bathymetry Beneath Ekström Ice Shelf, Antarctica: Implications for Glacial History and Ice‐Ocean Interaction
; ; ; Gaedicke, Christoph; ; ; ; ; ; ; Lambrecht, Astrid; Läufer, Andreas; ; ; ; (Geophysical Research Letters, 2020-05-20)
The shape of ice shelf cavities are a major source of uncertainty in understanding ice‐ocean interactions. This limits assessments of the response of the Antarctic ice sheets to climate change. Here we use vibroseis seismic ... -
Detectability of Artificial Ocean Alkalinization and Stratospheric Aerosol Injection in MPI‐ESM
; ; ; ; (Earth's Future, 2020-10-24)
To monitor the success of carbon dioxide removal (CDR) or solar radiation management (SRM) that offset anthropogenic climate change, the forced response to any external forcing is required to be detectable against internal ... -
Detecting Climate Change Effects on Vb Cyclones in a 50-Member Single-Model Ensemble Using Machine Learning
; ; Hofstätter, M.; ; Ludwig, R. (Geophysical Research Letters, 2019)
Vb cyclones are major drivers of extreme precipitation and floods in the study area of hydrological Bavaria (Germany). When assessing climate change impacts on Vb cyclones, internal variability of the climate system is an ... -
Detecting Cold Pool Family Trees in Convection Resolving Simulations
;; (Journal of Advances in Modeling Earth Systems, 2024-01-27)
Abstract Recent observations and modeling increasingly reveal the key role of cold pools in ...

Detecting initial aragonite and calcite variations in limestone–marl alternations
; ; ; (Sedimentology, 2021-05-28)
Limestone–marl alternations are commonly used for high‐resolution cyclostratigraphic studies and palaeoenvironmental reconstructions, but diagenetic studies indicate that not all limestone–marl alternations reflect genuine ... -
Detecting very slow natural ground motion in Schleswig-Holstein from radar satellite data
; ; (2021)
The near-surface geology of northern Germany is characterized by glacial deposits, deformed by rising Permian and Upper Triassic salt structures. Ground motions potentially associated with salt tectonic processes are very ... -
Detection Limits and Near-Field Ground Motions of Fast and Slow Earthquakes
; (Journal of Geophysical Research: Solid Earth, 2020)
We investigate theoretical limits to detection of fast and slow seismic events, and spatial variations of ground motion expected from M 6 earthquakes at short epicentral distances. The analyses are based on synthetic ... -
Detection of Copper by the ChemCam Instrument Along Curiosity's Traverse in Gale Crater, Mars: Elevated Abundances in Glen Torridon
; ; ; ; ; ; ; ; ; ; (Journal of Geophysical Research: Planets, 2023-03-07)
Laser‐induced breakdown spectroscopy, as utilized by the ChemCam instrument onboard the Curiosity rover, detected enhanced abundances of the element copper. Since landing in Gale crater (6 August 2012), 10 enhancements in ... -
Detection, Analysis, and Removal of Glitches From InSight's Seismic Data From Mars

The instrument package SEIS (Seismic Experiment for Internal Structure) with the three very broadband and three short‐period seismic sensors is installed on the surface on Mars as part of NASA's InSight Discovery mission. ... -
Determination of an arrival time cut for the separation of electrons and muons in extensive air showers
(Univ. Siegen, 2006)Extensive air showers measured by the KASCADE-Grande experiment at the Forschungszentrum Karlsruhe are studied with respect to the arrival times of electrons and muons at observation level. KASCADE-Grande is a ground based ... -
